But let us see also the words, what is said; “He brought again the thirty pieces of silver to the chief priests, and says, I have sinned in that I have betrayed innocent blood. And they said, what is that to us? See thou to that. And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.”
For neither could he bear his conscience scourging him. But mark, I pray you, the Jews too suffering the same things. For these men also, when they ought to have been amended by what they suffered, do not stop, until they have completed their sin. For his sin had been completed, for it was a betrayal; but theirs not yet. But when they too had accomplished theirs, and had nailed Him to the cross then they also are troubled; at one time saying, “Write not, this is the king of the Jews” (and yet why are you afraid? Why are you troubled at a dead body that is nailed upon the cross?); at another time they guard over Him, saying, “Lest His disciples steal Him away, and say that He is risen again; so the last error shall be worse than the first.” And yet if they do it, the thing is refuted, if it be not true. But how should they say so, which did not dare so much as to stand their ground, when He was seized; and the chief of them even thrice denied Him, not bearing a damsel's threat. But, as I said, the chief priests were now troubled; for that they knew the act was a transgression of the law is manifest, from their saying, “See thou to that.”
Hear, you covetous, consider what befell him; how he at the same time lost the money, and committed the sin, and destroyed his own soul. Such is the tyranny of covetousness. He enjoyed not the money, neither the present life, nor that to come, but lost all at once, and having got a bad character even with those very men, so hanged himself.
But, as I said, after the act, then some see clearly. See at any rate these men too for a time not willing to have a clear perception of the fact, but saying, “See thou to that:” which thing of itself is a most heavy charge against them. For this is the language of men bearing witness to their daring and their transgression, but intoxicated by their passion, and not willing to forbear their satanical attempts, but senselessly wrapping themselves up in a veil of feigned ignorance.
For if indeed these things had been said after the crucifixion, and His being slain, of a truth even then the saying would have had no reasonable meaning, nevertheless it would not have condemned them so much; but now having Him yet in your own hands, and having power to release Him, how could ye be able to say these things? For this defense would be a most heavy accusation against you. How? And in what way? Because while throwing the whole blame upon the traitor (for they say, “See thou to that”), being able to have set themselves free from this murder of Christ, they left the traitor, and even pressed the crime further, adding the cross to the betrayal. For what hindered them, when they said to him, “See thou to that,” themselves to forbear the criminal act? But now they even do the contrary, adding to it the murder and in every thing, both by what they do, and by what they say, entangling themselves in inevitable ills. For indeed after these things, when Pilate left it to them, they choose the robber to be released rather than Jesus; but Him that had done no wrong, but had even conferred on them so many benefits, they slew.
3. What then did that man? When he saw that he was laboring to no profit, and that they would not consent to receive the pieces of silver, “he cast them down in the temple, and went and hanged himself. And the chief priests took the pieces of silver, and said, it is not lawful for to put them into the treasury, because it is the price of blood. And they took counsel, and bought with them the potter's field to bury strangers in. Wherefore that field was called, the field of blood, unto this day. Then was fulfilled that which was spoken by Jeremy the prophet, saying, and they took the thirty pieces of silver, the price of Him that was valued, and gave them for the potter's field, as the Lord appointed me.”
Do you see them again self-condemned by their conscience? For because they knew that they had been buying the murder, they put them not into the treasury, but bought a field to bury strangers in. And this also became a witness against them, and a proof of their treason. For the name of the place more clearly than a trumpet proclaimed their blood- guiltiness. Neither did they it at random, but having taking counsel, and in every case in like manner, so that no one should be clear of the deed, but all guilty. But these things the prophecy foretold from of old. Do you see not the apostles only, but the prophets also declaring exactly those things which were matters of reproach, and every way proclaiming the passion, and indicating it beforehand?
This was the case with the Jews without their being conscious of it. For if they had cast it into the treasury, the thing would not have been so clearly discovered; but now having bought a piece of ground, they made it all manifest even to subsequent generations.
Hear ye as many as think to do good works out of murders, and take a reward for the lives of men. These almsgiving are Judaical, or rather they are Satanical. For there are, there are now also they, that take by violence countless things belonging to others, and think that an excuse is made for all if they cast in some ten or a hundred gold pieces.
Touching whom also the prophet says, “You covered my altar with tears.” Christ is not willing to be fed by covetousness, He accepts not this food. Why do you insult your Lord, offering Him unclean things? It is better to leave men to pine with hunger, than to feed them from these sources. That was the conduct of a cruel man, this of one both cruel and insolent. It is better to give nothing, than to give the things of one set of persons to others. For tell me, if you saw any two persons, one naked, one having a garment, and then having stripped the one that had the garment, thou were to clothe the naked, would you not have committed an injustice? It is surely plain to every one. But if when you have given all that you have taken to another, you have committed an injustice, and not shown mercy; when you give not even a small portion of what you rob, and callest the deed alms, what manner of punishment will you not undergo? For if men offering lame brutes were blamed, what favor will you obtain doing things more grievous? For if the chief, making restitution to the owner himself, still does an injustice, and so does an injustice, as by adding fourfold scarcely to do away the charge against himself, and this under the old covenant; he that is not stealing, but taking by violence, and not even giving to him that is robbed, but instead of him to another; nor yet giving fourfold, but not so much as the half; and moreover not living under the old dispensation, but under the new; consider how much fire he is heaping together upon his own head. And if he do not as yet suffer his punishment, for this self-same thing I say bewail him, for he is treasuring up against himself a greater wrath, unless he repent. For what? “Think ye,” says He, “that they alone were sinners upon whom the tower fell down? Nay, I say unto you, but except ye repent, you also shall suffer the same things.”
